Send DS1 Payload Pattern with BER Test

Syntax: send ds1 <n> payload <allonesallzerosf1in8p2e11p2e15p2e23qrss> test

Field	Description
n	DS1 number, 1 to 32, or a range of numbers such as 2-8.
allones	Send framed all-ones pattern. This can be used as a “keep alive”
	signal, idle code, and in measuring the T1 power level.
allzeros	Send framed all-zeros pattern. This can be used to test T1 circuits
	for B8ZS clear channel capability and to find equipment
	incorrectly set to AMI line code.
	Note: When using an all-zeros pattern, a T1 test set (such as a
	T-Berd 224 or Sunset T3) must be used to monitor for errors in
	the all-zeros pattern from the Access Navigator or looped back
	from a far-end network element.
f1in8	Send framed 1-in-8 pattern (also called a 1-and-7 pattern) in
	which each payload byte contains the bit pattern 01000000.
	(Minimal ones density test for T1 circuits with AMI coding.)
	Note: You must wait 30 seconds after the prompt appears before
	doing another test.
p2e11	Send 211–1 pattern with a maximum of 10 consecutive zeros and
	11 consecutive ones. (Minimum stress testing.)
p2e15	Send 215–1 pattern with a maximum of 14 consecutive zeros and
	15 consecutive ones. (Provides maximum number of consecutive
	zeros permissible in framed, non-B8ZS testing.)
p2e23	Send 223–1 pattern with a maximum of 22 consecutive zeros and
	23 consecutive ones. (Maximum stress testing.)
qrss	Send QRSS pattern (a modified 220–1) with a maximum of 14
	consecutive zeros and 20 consecutive ones. (Common stress test
	for T1 data applications.)

For most patterns, the CLI will provide a progress message indicating the success (ok) or failure of the command followed by the test results, as in the following samples.

Message: Waiting for pattern sync........ok.
